Specification of Letters Patent. PateI l'ted Sept. 27,1921.

Application filed March 7, 1921. Serial -N0.'450,21-2.

T 0 all whom it may concern.

Be it known that I, HowARD M. SHADE, a citizen of the United States,residing at Conemaugh, in the county of Cambria and State ofPennsylvania, have invented new and useful Improvements inTrack-Sanders, of which the following is a specification:

This inventionrelates to a sander device for locomotives, the generalobject of the invention being to provide air-blast means for forcing thesand from a pocket connected with the sand dome to the delivery pipes.

Another object of the invention is to provide means for adjustingthenozzles of the air blast means so as to regulate the amount of sanddischarged into the delivery pipes.

A further object of the invention is to provide means for screening thesand passing through the pockets so that the sand entering the deliverypipes is free of all coarse particles.

Another object of the invention is to provide means for delivering thesand either .in front of the wheels, for the forward movement of thetrain, or'in rear of the wheels for the reverse movement of thetrain.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claims.

In describing my invention'in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding arts throughout the several views, and in which- Figure lis a diagrammatic view showing my invention applied to a locomotive.

Fig. 2 is a diagrammatic end view showing the invention applied to alocomotive.

througha sand pocket and its associated parts, the section being takenon line 3-3 .vided with Fig. 3 is a longitudinal sectional View of Fig.3.

In these views 1 indicates a pocket which isin communicationwith thesand dome A of the locomotive and which is secured in place in anysuitable manner. I i prefer one of these pockets at each side of thelocomotive. Each of these pockets comprises an upper part 2. and a lowerpart 3, the adjacent ends of which are provided with flanges 4," theflange of the upper part 2' overlapping the flange of the lower part soas to provide a-water-shed and the flanges are bolted together-with thegasket 5 between them so as to make a water-tight joint. 7 A partition 6is arranged in part 2 adjacent the bottom thereof which is proan opening7 for permitting the sand to pass into the lower part 3. This opening iscontrolled by a gate 8 to which is connected an operating rod 9 whichpasses through a gland nut 10 in part 2, the projectingend of therod'being provided with a'handle 11. Thus the fiow of sand from theupper part of the pocket to the lower part can be controlled or it canbe entirely shut off so as ,to permit the removal of the lower part ifnecessary.

A perforated plate or screen 12 is inclinedly supported :in the lowerpart 3 of the pocket by the ledge 13 so as to screen the 'the screenandthis hole being closed by a screw plug 15.

The bottom of part 3 of thepocket is provided with a central opening 16for delivering the sand to the three outlet ports 17, 18 and 19, adeflector 20 projecting into said opening for directingthe sand to thethree ports. This deflector is providedwith theqsubstantially T-shapedpassage 2l-and the substantially L-shaped passage22,- air beingusuppliedto the passage 21 by pipe 23 and to the passage 22 bypipe 24,; thesepipes being connected witlithe compressed controlled air supply of thetrain and by the valve 25 located in the cab and so arranged that aircan -be supplied to either the pipe; 23 or pipe 24' as desired. A pairof nozzles 26 are associated with i the passage 21 and a nozzle 27 isassociated with the passage 22, these nozzles being arranged to directthe air into the discharge ports 17 and 18 and 19, the blast coming fromeach nozzle carrying the sand along with it. Openings 28 are formed inthe bottom of the pocket adjacent the nozzles 26, said openings beingclosed by the. screw plugs 29.

Elbows 30 are provided for connecting the discharge ports with thedelivery pipes 31 which deliver the sand upon the rails adjacent thedrive wheels of the locomotive, as shown in Fig. 1. These elbows areprovided with flanges 32 which are bolted to the pocket, gaskets 33being provided for making a tight joint. The elbows are provided withremovable caps 34; which are bolted to the elbows, these caps being soarranged as to receive the impact of the' sand being forced through thedischarge ports and elbows by the air blast. Thus the caps can bereplaced by new ones when they have become worn by the sand.

The nozzles 26 and 27 are screwed into the passages and this permits thenozzles to be adjusted by screwing them in orout and thus the flow ofsandto the track can be controlled as when'the nozzles are movedoutwardly less sand will be forced into the delivery pipes than when thenozzles are screwed in. The wrench for screwing and unscrewing saidnozzles can be passed through the holes 28 or through the elbows afterremoving the caps 34.

It will thus be seen that the flow of sand from the upper part of thepocket to the lower part can be controlled by the sliding gate orentirely shut off by said gate so as v to permit removal of the lowerpart of the pocket. The screen will separate all the coarse particles sothat the sand passing into the discharge ports will be free of largeparticles and thus the danger of stoppage of these ports will beeliminated.

By manipulating the: valve 25 the air blast will carry the sand from thedischarge ports through the elbows into the delivery pipes and dischargeit upon the track either in front of the drive wheels or in rearthereof, as desired. By adjusting the nozzles the amount of sanddelivered can be controlled and due to the flanges and gaskets there isno danger of the sand within the device becoming wet, and thus failingto flow.

In the modification shown in Fig. 5, substantially T-shaped pipes 35 arescrewed into the bottomof the'pocket and the elbows 8,0 are screwed tothese pipes. The nozzles 26' are also screwed in the pipes so as todirect the air blast toward the elbows. These nozzles can be adjustedfrom the exterior as they are provided with wrench receiving parts 36and with lock nuts 37. In this'form the bottom of the pocket is providedwith a clean-out hole closed by a screw plug 38 and the pipes 35 arealso provided with clean-out holes closed by plugs 39. In other respectsthis form of the invention is similar to that before described.

In the modification shown in Fig. 6, the elbows are eliminated and oneend of each pipe 35 is curved to engage directly the delivery pipe. Inother respects this form of the invention is similar to that shown inFig. 5. Fig. 7 shows an elbow 30 threading into the discharge port ofthe pocket and having its outer end provided with a screw threadedpocket to receive the screw threaded end of the delivery pipe. In thisform when the elbow is worn by the sand it can be removed and replacedby a new one.

It is thought from the foregoing description that the advantages andnovel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the constructionand in the combination and arrangement of the several parts, providedthat such changes fall within the scope of the appended claims.

What I claim is 1. A device of the class described comprising a pocketformed of an upper and lower part, means for connecting the two partstogether in a water proof manner, means for controlling the flow of sandfrom the upper part to the lower part, a screen in thelower part, meanspermitting the removal of the coarse material from the screen, adelivery pipe connected'with the bottom of the lower part an air blastmeans for forcing the sand from the said lower part into the deliverypipe.

2. A device of the class described comprising a bracket having adischarge opening in its bottom, a deflector extending into saidopening, said bottom having three outlet ports therein communicatingwith the opening and the deflector having a T- shaped port therein andan L-shaped port therein, a pair of nozzles adjustably mounted in theT-shaped port, a nozzle adjustably mounted in the L-shaped port, saidnozzles being arranged to discharge into the three ports abovementioned, means for supplying compressed air to the T and L-shapedports and delivery pipes connected with the three ports above mentioned.

In testimony whereof I afiix my signature. i

' HOWARD M. SHADE.
